Macalester's Administrator v. Maryland & Others was a case heard by the United States Supreme Court in 1885. The case involved a dispute between the administrator of the estate of a deceased Maryland resident and the state of Maryland. The administrator of the estate had filed a claim against the state for the recovery of certain bonds that had been issued by the state. The state argued that the bonds were not valid and that the administrator had no right to recover them. The Supreme Court held that the administrator had a valid claim and that the state was liable for the bonds. The Court also held that the state was not entitled to any immunity from suit and that the administrator was entitled to recover the bonds. The Court also held that the state was not entitled to any special privileges or immunities from suit. This case established the principle that states are not immune from suit and that individuals have the right to sue states for the recovery of debts.

In Macalester's Administrator v. Maryland & Others, the Supreme Court was tasked with determining whether a state court had jurisdiction to hear a case involving an estate located in another state. The majority opinion held that the lower court did not have jurisdiction because it lacked personal service of process on all parties involved and thus violated due process rights under the Fourteenth Amendment. However, Justice Field dissented from this decision and argued that since there were no objections raised by any party regarding lack of personal service or other jurisdictional issues during trial proceedings, then those issues should be considered waived and therefore the judgment should stand as valid. He further argued that if such procedural defects could be used to invalidate judgments after they are rendered then it would create uncertainty for litigants who rely on finality of judgments when making decisions about their cases going forward.
